ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a data processing apparatus having an annotation display function that reduces or enlarges the display image of the annotation pasted on a text as a result of being inputted through the annotation input window and that superposes the display image with the changed magnification in a specified position on the display image on the text display screen.
With a conventional data processing apparatus with an annotation display function that displays the annotations pasted on text, in a case where the user carries out the operation of pasting an annotation in a specific position on text, the annotation being entered on a window screen (an annotation input window), when the user displays the text again, a mark (an annotation mark)
22
indicating the fact that the annotation has been pasted is displayed as shown in FIG.
22
.
When the user wants to check the contents of the annotation pasted in the position in which the annotation mark
22
appears, the user has to click the mark
22
to display the window screen again and check the contents of the annotation.
As described above, with the conventional data processing apparatus with an annotation display function, when an annotation is pasted on text, only a mark indicating that the annotation has been pasted is displayed on the text display screen as shown in FIG.
22
. The mark alone prevents the user from checking the contents of the annotation written in the text at a single glance. Thus, the user has to repeat troublesome operations: that is, the user has to take the trouble to click the mark to display the contents of the annotation again on the window screen, check the contents, and then erase the window screen again to read the text.
BRIEF SUMMARY OF THE INVENTION
It is, accordingly, an object of the present invention to provide a data processing apparatus with an annotation display function that enables the user to check the contents of annotations while reading the text, by reducing or enlarging the display image of an annotation input window with a specified magnification in displaying annotations and by superposing the display image in a specified position on a text display image on a text display screen.
Another object of the present invention is to provide a data processing apparatus with an annotation display function that enables the user to check the contents of annotations easily even when a simple reduction of annotations makes the annotations illegible because annotation data items in the annotations overlap with each other, by displaying a reduced display image of the annotations from which the overlap of annotation data items has been removed.
Still another object of the present invention is to provide a data processing apparatus with an annotation display function that enables the user to check the contents of annotations easily even when a simple reduction of annotations makes the annotations illegible because the size of annotation data items in the annotations is small, by reducing or enlarging only the area from which blanks have been removed and thereby making the contents of the annotations larger with the entire display size remaining unchanged.
Still another object of the present invention is to provide a data processing apparatus with an annotation display function that enables the user to check the contents of annotations easily by sensing annotation data items whose contents would be difficult to check if the annotations were simply reduced and displayed with a specified magnification because the display size is small and by using the smallest magnification that prevents the display size after the magnification change from being smaller than a display limit value for the annotation data items, thereby displaying the contents of the annotations larger with the entire display size remaining unchanged.
A data processing apparatus with an annotation display function according to the first aspect of the present invention is characterized by comprising: annotation input means for taking in the individual data items constituting an annotation pasted in a specified annotation position (annotation writing position) on a text as a result of the annotation being inputted from an annotation input window and acquiring the input positions of the annotation data items and information on their size; annotation image magnification change means for changing the display magnification of a display image of the annotation on the basis of the input positions of the individual annotation data items in the annotation and information on their size acquired by the annotation input means and a specified magnification; and text and annotation image display means for putting and displaying the display image of the annotation whose magnification has been changed by the annotation image magnification change means in the specified annotation position on a text display image. The specified magnification may be prepared beforehand in the system (a system-specified magnification) or a user-specified magnification. When the user does not specify any magnification in particular, a default magnification may be used. When the user has specified a magnification, the magnification may be used in place of the default magnification.
With such a configuration, the annotation image magnification change means creates a reduced or enlarged image of the display image of the annotation on the basis of the input positions of the individual annotation data items in the annotation and information on their size acquired by the annotation input means. The reduced or enlarged display image of the annotation is put and displayed in the specified annotation writing position on a text display image by the text and annotation image display means. The size of the reduced or enlarged display image of the annotation is the size of the annotation input window at annotation setting reduced or enlarged with the specified magnification.
Because the reduced or enlarged display image of the annotation can be superposed on the display image of the text on the text display screen, the user can check the contents of the written annotation while reading the text and need not take the trouble to use another window only for the purpose of checking the contents of the annotation, differently from a conventional equivalent.
In a case where the size of the annotation display image on the text display screen is made changeable, for example, when the contents have been checked, the user can reduce the size of the annotation display image substantially to make a display as if the conventional annotation mark were displayed. By the user's operation, all of the annotation display image or only the user-specified annotation display image on the text display screen may be erased.
A data processing apparatus with an annotation display function according to the second aspect of the present invention is such that annotation data display overlap removing means for sensing an area where at least two annotation data items overlap with each other, determining only one data item to be displayed in the overlapping area, and acquiring specific information indicating the overlapping area and an annotation data item to be displayed in the area is added to the data processing apparatus with an annotation display function according to the first aspect. The data processing apparatus of the second aspect is characterized in that the annotation image magnification change means changes the display magnification of a display image of the annotation where the display image portion of the annotation data items except for the annotation data item to be displayed in the overlapping area has been subtracted from the overlapping area indicated by the specific information acquired by the annotation data display overlap removing means and the display image of the annotation whose magnification has been changed is put and displayed in the specified annotation position on a text display image.
The approach of sensing an area where at least two annotation
